A staircase is provided that includes a column and steps. Each step: is coupled to the column and extends outside of, and away from, the column; includes a tread surface; and can move longitudinally along the column. The staircase can transition to a plurality of states by an actuation system, including closed and open states. The closed state includes the steps positioned at the upper end with the tread surfaces of the plurality of steps oriented around the upper end and coplanar to a flooring surface of the upper floor. The opened state includes the steps positioned at varying distances longitudinally along the column from the upper end towards the lower end so as to form spiraling steps around the column between the upper and lower floors. The steps can move longitudinally along the column for positioning in the closed and opened states.

A self-leveling staircase. The staircase has a first flight of self-leveling steps having a first end adjacent to the ground and a plurality of stair treads pivotally attached at a right edge to a first pair or stair rails and at a left edge to a second pair of stair rails. A self-leveling platform is pivotally attached on a second end of the first flight of self-leveling steps and to the first and second pair of stair rails. A second flight of self-leveling steps having a first end is pivotally attached to an opposite side of the self-leveling platform from the first flight of self-leveling steps. The second flight of self-leveling step has a plurality of stair treads pivotally attached at a right edge to a third pair of stair rails and pivotally attached at a left edge on front and back ends thereof to a fourth pair of stair rails.

A freestanding, adjustable, modular spiral staircase embodied in a unique method of spiral staircase design is provided. The steps of the spiral staircase are arrayed and supported in a circular pattern around a central column with the outside edges or leading or trailing corners of the steps are supported by three peripheral columns, while step posts interconnect adjacent steps. Many parts are interchangeable and the steps adjustable to allow for shortening or lengthening the staircase. The base of the staircase unit is heavy to provide maximum stability and to prevent tipping.
